The wife's body is provided with a through passage for passengers to move between vehicles. The roof structure 4 is disposed on the upper edge side of the side structure 3 and the end structure as a structure forming a roof portion of a vehicle. In the roof structure 4, an outdoor unit of an air conditioner for adjusting the temperature in the vehicle, a pantograph, and the like are installed.

  Further, as shown in FIGS. 1 and 2, the railway car structure 1 includes a floor portion 21, a connecting member 22, and a restricting member 23. As shown in FIG. 2, the floor surface portion 21 is a portion that constitutes the floor surface of the passenger compartment S, and is used for the passage of passengers and the like and the fixation of the seat 6. The floor portion 21 is disposed at a position above the floor assembly 2 at a fixed distance from the floor assembly 2. In the present embodiment, the floor portion 21 is divided into rows of the seats 6 arranged in the longitudinal direction of the vehicle. That is, a plurality of floor portions 21 are arranged in the longitudinal direction of the vehicle, and the seats 6 in the respective rows are respectively installed to the floor portions 21. Adjacent floor surface portions 21 may be connected, for example, by rivets, or may be connected via an elastic member such as a sponge. When a rivet is used, for example, an overhanging portion may be provided on the upper surface portion of one floor portion 21 and the bottom portion of the other floor portion 21, and the upper and lower overhanging portions may be connected by rivets. When an elastic member is used, for example, the elastic member may be disposed between the side surfaces of the floor portion 21. An overhanging portion is provided on the upper surface portion of one floor surface portion 21 and the bottom surface portion of the other floor surface portion 21. The elastic member may be disposed between the upper and lower overhanging portions.

  The connecting member 22 is a member that connects the side structure 3 and the floor portion 21. For example, a wire, a rod-like member, or a band-like member can be used as the connection member 22. The connection member 22 may be formed of a metal material, or may be formed of a resin material such as a carbon fiber reinforced plastic. The connecting member 22 may be a member having a certain stretchability in the longitudinal direction. The connecting member 22 is suspended between the outer plate 11 and the inner plate 12 in each of the left and right side structures 3 as shown in FIG. Further, as shown in FIG. 2, the connecting members 22 are disposed at positions corresponding to the blow-off panels 15, and are disposed in the front and rear pair so as to sandwich the seat 6 with respect to the floor surface portion 21. The floor surface portion 21 is suspended from the side structure 3 by a total of four connecting members 22 in front and rear and right and left directions, and can swing relative to the floor structure 2.

  In the present embodiment, the upper end portion 22 a of the connecting member 22 is swingably connected to the inner surface of the outer plate 11 at a position higher than the lower edge of the window 13, for example. Further, the lower end portion 22 b of the connecting member 22 is swingably connected, for example, to the upper edge side of the side surface in the width direction of the floor portion 21. When a member having sufficient rigidity is used as the connecting member 22, for example, a hinge can be used to connect the connecting member 22 and the outer plate 11 and to connect the connecting member 22 and the floor portion 21. Moreover, when using a member with poor rigidity as the connecting member 22, for example, a pin can be used for the connection between the connecting member 22 and the outer plate 11 and the connection between the connecting member 22 and the floor portion 21.

  The restricting member 23 is a member that restricts the displacement of the connecting member 22 in the horizontal plane within a certain range. The attachment position of the restriction member 23 in the longitudinal direction (height direction of the vehicle) of the connection member 22 is not particularly limited, but as the attachment position of the restriction member 23 approaches the lower end side of the connection member 22, the horizontal surface of the connection member 22 The effect of restricting the displacement of the connecting member 22 in the horizontal plane decreases as the mounting position of the restricting member 23 approaches the upper end side of the connecting member 22. In the present embodiment, as shown in FIG. 2, the control members 23 are disposed at two positions, upper and lower, corresponding to the position of the lower edge of the window 13 and the position of the seat surface of the seat 6.
